Hi All, I have been a Mossberg owner for a good 30+ years. I now have a new 930 with an 18 inch barrel, 5 shot, home defender model. At this point in life I find myself spending a good part of my life in a wheel chair. I have shot my 500 a number of times while in my chair which I have found to be interesting at several levels. My biggest problem is the felt recoil. It can actually move my chair backwards in a circular movement (I'm right handed). I would like to have the barrel PORTED to lessen the felt recoil. Does anyone have any info on who, and where I can have this done? OR any other solution that will work. (a girl at Mossberg says they won't do a barrel 18 inches long). I would really appreciate any help anyone can give. Thanx. Bill
